Shallow River Paddling is a term used to describe what someone looks like while having sexual intercourse. The term was coined during a canoe trip down a river with a very low water level. When a river’s water level is very low a person’s floating vessel may become stuck on rocks and other debris. When this happens he/she must violently thrust his/her hips in a manner resembling a dog violently humping its un-consenting victim to free the vessel from being stuck. This is the act of “Shallow River Paddling” or SRP for short.
